.omp.json 中的命令段 Oh-my-posh 主题

Question

我一直在根据自己的口味修改主题 kali，来自 oh my posh。

我遇到了以下问题。

我有这个片段

{
  "type": "prompt",
  "alignment": "left",
  "segments": [
    {
      "type": "command",
      "style": "plain",
      "foreground": "#ffffff",
      "properties": {
        "shell": "cmd",
        "command": "cmd /C D:\\repos\\zsh-pwsh-wt\\windows-pws-posh\\center.bat"
      },
      "template": "{{ .Output }}"
    }
  ]
},

该段的要点是打印一条与主提示上方的窗口一样宽的线。由于与 pwsh 的兼容性问题，我通过 cmd 进行操作。

文件

center.bat

可以完美地工作，按其应有的方式打印该行。 问题是，当我调用该脚本文件时，它打印的行比窗口宽度短。

以下是示例：

• 直接运行脚本：

• 添加段/块：

此外，这个示例场景：

• 当我单独运行

  center.bat

  时，宽度为 172。
• 当从

  omp.json

  运行时，它是120。

再次检查，当它从模板运行时，无论窗口大小如何，它总是返回 120。

• 模板：

脚本：

@echo off
setlocal enabledelayedexpansion
set width=0

:: Get the current window width (number of columns)
for /f "tokens=2 delims=:" %%I in ('mode con ^| findstr "Columns"') do set width=%%I

:: Set the initial TEXT value to be repeated
set TEXT=─

:: Initialize an empty string to hold the repeated TEXT
set result=

:: Loop through the window width and append the TEXT to the result string
for /L %%i in (1,1,!width!) do (
    set result=!result!!TEXT!
)

:: Now echo the final string in one go
echo !result!
endlocal

编辑： 我已经尝试了很多，我尝试将宽度作为参数传递给 .bat，它本身可以工作，但在模板中不起作用，至少在我传递参数时不起作用。 因此，我决定仅通过 $Profile 来完成此操作，但仅在提示开始时才起作用：

oh-my-posh init pwsh --config 'D:\repos\zsh-pwsh-wt\windows-pws-posh\kalimod.omp.json' | Invoke-Expression
function prompt {
    $width = [console]::WindowWidth
    $result = "-" * $width
    [System.Environment]::SetEnvironmentVariable("PROMPT_LINE", $result, [System.EnvironmentVariableTarget]::Process)

    write-Host($result)
oh-my-posh init pwsh --config 'D:\repos\zsh-pwsh-wt\windows-pws-posh\kalimod.omp.json' | Invoke-Expression

    # Output the custom prompt (optional to display additional info)
    #return $line
}

# This line ensures the prompt is re-executed after each command is run
$ExecutionContext.InvokeCommand.CommandNotFoundAction = {
    # Force a prompt redraw after each command
    prompt

}

已解决。 感谢@Compo 的观察。 我放弃了 .bat 脚本方法。 最终的解决方案，我在 .ps1 配置文件中创建一个事件，该事件在每次命令（除了其本身）运行时运行，计算当前窗口宽度并将其保存在可从 omp.json 主题文件访问的全局变量中。 这是代码：

oh-my-posh init pwsh --config 'D:\repos\zsh-pwsh-wt\windows-pws-posh\kalimod.omp.json' | Invoke-Expression
$width = [console]::WindowWidth
    $result = "ˍ" * ($width-1)
    [System.Environment]::SetEnvironmentVariable("PROMPT_LINE", $result, [System.EnvironmentVariableTarget]::Process)
Register-EngineEvent -SourceIdentifier PowerShell.OnIdle -Action {
    $width = [console]::WindowWidth
    $result = "ˍ" * ($width-1)
    [System.Environment]::SetEnvironmentVariable("PROMPT_LINE", $result, [System.EnvironmentVariableTarget]::Process)
    oh-my-posh init pwsh --config 'D:\repos\zsh-pwsh-wt\windows-pws-posh\kalimod.omp.json' | Invoke-Expression
}

这是该块以及我在主题中如何称呼它：

   {
  "type": "prompt",
  "alignment": "left",
  "segments": [
    {
      "type": "command",
      "style": "plain",
      "foreground": "#ffffff",
      "properties": {
        "shell": "powershell",
        "command": "$env:PROMPT_LINE"
      }
    }
  ]
},
